7056ec6bfd runtime: fix floating point exception on Plan 9 
Change 5660047 moved an FLDCW instruction
that disables invalid operand traps into
runtime·asminit, which is called from
runtime·mstart. Thus, runtime·check is being
called prior to setting the appropriate control bits,
which on any QNaN comparison will cause Plan 9
to take an invalid operand trap. This change loads
the control bits (for Plan 9) prior to runtime·check.
Ideally, this should be done before the QNaN checks
on any system, but possibly other kernels simply
don't ever trap on invalid operands.

e530d6a1e0 6c, 6g, 6l: add MOVQL to make truncation explicit 
Without an explicit signal for a truncation, copy propagation
will sometimes propagate a 32-bit truncation and end up
overwriting uses of the original 64-bit value.

The case that arose in practice is in C but I believe
that the same could plausibly happen in Go.
The main reason we didn't run into the same in Go
is that I (perhaps incorrectly?) drop MOVL AX, AX
during gins, so the truncation was never generated, so
it didn't confuse the optimizer.

Fixes #1315.
Fixes #3488.

30bc5d7bbd cmd/8c: fix store to complex uint64 ptr 
Assignment of a computed uint64 value to an
address derived with a function call was executing
the call after computing the value, which trashed
the value (held in registers).

long long *f(void) { return 0; }
void g(int x, int y) {
        *f() = (long long)x | (long long)y<<32;
}

Before:

(x.c:3)	TEXT	g+0(SB),(gok(71))
...
(x.c:4)	ORL	AX,DX
(x.c:4)	ORL	CX,BX
(x.c:4)	CALL	,f+0(SB)
(x.c:4)	MOVL	DX,(AX)
(x.c:4)	MOVL	BX,4(AX)

After:
(x.c:3)	TEXT	g+0(SB),(gok(71))
(x.c:4)	CALL	,f+0(SB)
...
(x.c:4)	ORL	CX,BX
(x.c:4)	ORL	DX,BP
(x.c:4)	MOVL	BX,(AX)
(x.c:4)	MOVL	BP,4(AX)

Fixes #3501.

c9529e02c1 time: in Format give buffer an initial capacity 
I have a small web server that simply sets several cookies
along with an expires header, and then returns.  In the
cpuprofile for a 200k request benchmark, time.Time.Format()
was showing up as 8.3% of cpu usage.  Giving the buffer an
inital capacity to avoid reallocs on append drops it down to
7.6%.

22690e6621 crypto/rsa: only enforce that de ≡ 1 mod |(ℤ/nℤ)*| in order to load private keys generated by GnuTLS. 
Previously we checked that de ≡ 1 mod φ(n). Since φ(n) is a multiple
of |(ℤ/nℤ)*|, this encompassed the new check, but it was too strict as
keys generated by GnuTLS would be rejected when gcd(p-1,q-1)≠1.

(Also updated the error strings in crypto/rsa to contain the package name, which some were missing.)
